详解如何在阿里云上安装mysql
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>mysql作为轻量级开源数据库，在企业级的应用中非常的广泛。我之前用过mssql，oracle，postgresql，mysql。目前阿里云上面暂时没有oracle。就我个人使用情况来看，创建项目我会首选mysql。</p>

卸载已有的mysql</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
系统中可能早已存在mysql数据库，所以在安装之前我们需要将其卸载掉。</p>

<pre class="brush:bash;">
# rpm -qa|grep -i mysql</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
该命令将显示已经安装了的mysql软件，之后通过下面的命令将软件一个一个卸载掉就可以了。注意：这样的卸载是不彻底，不过这里够用了。</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:bash;">
# yum remove '软件名'</pre>
</div>

今天就简单介绍下在阿里云上安装mysql的步骤。我个人的操作系统是阿里云ecs的CentOs，首先从官网下载安装mysql-server:</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:bash;">
wget http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
rpm -ivh mysql-community-release-el7-5.noarch.rpm
yum install mysql-community-server</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
安装成功后，重启mysql：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:bash;">
service mysqld restart</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
初次安装是没有密码的，我们需要为root设置密码，首先切换到mysql命令：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:sql;">
mysql -u root</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
设置密码：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:sql;">
mysql>set password for ‘root‘@'localhost' =password(‘password');</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
远程连接设置，默认是不允许所有ip都允许远程连接的：</p>
<div class="jb51code" style='margin: 0px; padding: 0px; outline: none; line-height: 25.2px; font-size: 14px; width: 660px; overflow: hidden; clear: both; font-family: tahoma, arial, "Microsoft YaHei";'>
<pre class="brush:sql;">
mysql> grant all privileges on *.* to root@'%'identified by ‘password';</pre>
</div>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
最新的阿里云内网入方向全部规则已经不需要设置了，已经允许mysql默认3306端口了。</p>
<p style='margin: 0px; padding: 5px 0px; outline: none; font-size: 14px; line-height: 30px; font-family: tahoma, arial, "Microsoft YaHei";'>
